Now we know why Scarlett Johansson always has a smile on her face: she's taken up tantric sex with boyfriend Josh Hartnett. The Match Point beauty's indiscreet beau made headlines this week when he revealed: "A really dirty friend of mine gave me a book on tantric sex for my birthday. I studied it to see what all the fuss was about. It's not easy but it's all good." SOURCE: THE SUN
